Transcript of river pollution

river pollution
what is it?
it is when the water is polluted by human or animal waste.
how does it affect us?
the water it is the main resource and the most important thing we need to live. But if its polluted , we cannot use it.
here is a video

how can we help to solve
as I show in the next video there are companies trying to solve this problem. you can help by donating or recycling.
the water pollution is increasing and its going to worse, but maybe with our help we can turn things around
Up to 90 % of wastewater in developing countries flows untreated into rivers, lakes and highly productive coastal zones, threatening health, food security and access to safe drinking and bathing water.
Sewage process Many industries “ some of them known to be heavily polluting (such as leather and chemicals) “ are moving from high-income countries to emerging market economies. Despite improvements in some regions, water pollution is on the rise globally.

trillion gallons of untreated sewage, storm water, and industrial waste are discharged into US waters annually.

drinking waters are a problem for about half of the world’s population. Each year there are about 250 million cases of water-based diseases, resulting in roughly 5 to 10 million deaths.

2010, there was a huge oil spill in America by BP. Of the 400 miles of Louisiana coast, approximately 125 miles have been polluted by the oil spill. Over 1,000 animals (birds, turtles, mammals) have been reported dead, including many already on the endangered species list. Of the animals affected by the spill that are still alive only about 6% have been reported cleaned, but many biologists and other scientists predict they will die too. In November 2012, BP agreed a settlement with the US government worth $4.5bn, including a $1.26bn criminal fine

sewage process Projected increases in fertilizer use for food production and in wastewater effluents over the next three decades suggest there will be a 10-20 percent global increase in river nitrogen flows to coastal ecosystems.
Sewage processing developing countries, 70% of industrial wastes are dumped untreated into waters where they pollute the usable water supply
40% of America’s rivers and 46% of America’s lakes are too polluted for fishing, swimming, or aquatic life.

In April 2010, The Transocean Oil Rig exploded, killing 11 workers. The disaster also damaged the Gulf of Mexico coast causing one of the biggest environmental disasters in US history. In January 2013, the company paid $400m (£248m) in criminal penalties and a $1bn civil fine after pleading guilty to violating the Clean Water Act.
in developing countries, 70 percent of industrial wastes are dumped untreated into waters where they pollute the usable water supply.

some facts
how the world uses freshwater:
• About 70 percent for irrigation
• About 22 percent for industry
• About 8 percent for domestic use

27% of the urban population in the developing world do not have piped water in their home
lack of safe water and sanitation in cities leads to cholera, malaria and diarrhea.
